The operator of Japan's stricken Fukushima nuclear power plant says it has suspended clean-up operations of radioactive water only hours after it started.
A spokesman for the Tokyo Electric Power Company said radiation levels had risen faster than expected.
The clean-up operation got under way on June 17 after being delayed by a series of problems at the Fukushima Daiichi plant, which was disabled by the March 11 earthquake and tsunami.
Officials had said earlier this week that large and growing pools of radiactive water at the plant, 240 kilometers northeast of Tokyo, were in danger of spilling into the sea within a week unless action was taken quickly.
